What is the gravitational force of the Milky Way?

And the main answer to the question: The FORCE between us(Milkyway) and Andromeda is anywhere between 1.91*10^29 Newtons to 14.31*10^29Newtons.

Does the Milky Way have a strong gravitational pull?

Scientists estimate there are about 200 billion stars in our galaxy, called the Milky Way. Each of these 200 billion stars has enormous mass, so they all exert a strong gravitational pull on each other. It’s gravity that keeps our galaxy together.

What would be the gravitational force on you if you were at the center of the Earth?

If you are at the center of the earth, gravity is zero because all the mass around you is pulling “up” (every direction there is up!).

Where is gravitational force highest?

poles
The distance of the equator from the center of the earth is greater than that of the poles. As a result, gravitational acceleration is lower at the equator as compared to the poles. Therefore, it is clear that the gravitational force is minimum at the equator and maximum at the poles.

What is at the center of the Milky Way quizlet?

The Galactic center appears to have: A stellar density a million times higher than near Earth. Apparently, there is a supermassive black hole in the center of our Galaxy. It is called Sagittarius A and has a mass of 4 million solar masses.

Is the Milky Way twisted?

Astronomers describe the Milky Way as a flat disk-shaped, double-armed spiral galaxy twirling and twinkling with stars.

What massive gravitational force can we found at the center of the galaxy?

Black holes are intriguing systems, and supermassive black holes and the dense stellar environments that surround them represent one of the most extreme places in our universe. The supermassive black hole that lurks at the center of our galaxy, called Sgr A*, has a mass of about 4 million times that of our Sun.

Does the Milky Way orbit something?

“The Moon orbits the Earth, the Earth orbits the Sun, the Sun orbits the center of the Milky Way, but does our galaxy orbit anything?” Our galaxy does indeed! The other large galaxy involved is Andromeda, our closest galactic neighbor; our galaxy and Andromeda are slowly orbiting each other.

How strong is gravity at center of earth?

At the very center, the gravitational force is zero because there’s equal mass pulling on you from all sides, and it all cancels. If you built a room there, you could float around freely. That’s what it means to say that gravity is zero at the center of Earth.

Is there gravity on earth yes or no?

Yes. There’s gravity everywhere – it’s an intrinsic property of all matter that has non-zero mass. If you were at the centre of the Earth it would feel like you were weightless. This is because all of the forces on you that result from the Earth’s gravity are balanced.

Why is gravity at center of earth zero?

Acceleration due to the earth’s gravity is zero at the centre of the Earth because at that point the mass of the earth is equally distributed in all directions, so pulling equally in all directions for a net zero pull. As the distance from the centre decreases, the acceleration due to gravity also decreases.

Does the Milky Way galaxy have a center of gravity?

, Reader. Yes, our Milky Way Galaxy has a center of gravity. It is at the center of the galaxy, where the central black hole (Sagittarius A*) resides. However; the center of gravity is computed by summing the galaxy’s entire mass.

How do you measure the mass of the Milky Way?

Measuring the mass of the Milky Way Measure the velocity v of a star orbiting on a circular orbit at distance r from the center of the Milky Way. Same formula:

What happens to velocity at the optical edge of a galaxy?

Inner galaxy: enclosed mass rises, so does the velocity Beyond the optical edge of the galaxythe galaxy: no stars, so no more mass, velocity falls Expected rotation curve of a galaxy if all the mass is due to observed stars and gas ASTR 1120: Spring 2006 Rotation curve of the Milky Way

Is there a black hole at the center of the Milky Way?

Yes, the center of mass of the Milky Way galaxy lies at Sagittarius A*; the black hole at that location is roughly 2–4 million solar masses in “dimension”. It lies 25,000 light years away at the center of the Milky Way.
